How are your HS playoffs structured?

We have 4 divisions (D1 largest schools, D4 smallest) everybody makes the tourney.  Sectional, District, Regional then State.  Sectional are tyipcally 2 games....though in some areas you can get a bye if the number of teams isn't even.  Better seeded team hosts the sectional games.   By the time the District starts, there are 64 teams left in each division.  Again, 2 games to get thru...at pre-scheduled sites (usually nicer fields).  Regionals have 16 teams in each division at 4 sites around the state.  4 Regional Champs in each Division advance to the State tourney held at Huntington Park, home of the AAA Columbus Clippers.  4 games each on Thursday and Friday....then 4 finals on Saturday to determine 4 State champs

We are in one of the NorCal sections.  We have a 4-team league tournament, which is basically meaningless, then each of the 6 divisions has a single-elimination tournament.  In the the small school divisions there are some truncated brackets, but Division 1 through 4  will have a field of 16.   In our league and Division at least ( Division 2) if you have a winning record in league, you will get a spot in that bracket. 

NC...64 teams in each class...4A down to 1A...single elimination all the way through to the semi-finals...then it becomes best 2/3.  There are 2-3 days between games.

In Texas we have 6A to 1A and also Tapps (private schools). 6a-2A has 4 teams from each district make the playoffs. There are 4 regions with a total of 64 teams. Regions 1&3 play for a state title and 2&4 play for the other. All 4 teams from the same district will be in the same region. Each round before state can either be a 1 game or 3 game series each week, determined by coin flips. Then at state it is single elimination. It's the same for 1A but with only 32 teams. Everything is determined by coin flips, # of games, location, and home team. You better hope luck is on your side.

My 2019's 5A team played and won 2 games in 1st round last week, 1-0 and 2-1. This week we have a 1 game Thursday.

Texas... This grouping/format applies to all major sports, I believe. Difference is baseball is usually two out of three to win the round.  I say usually, because a coach from one school can request a one game series, if the other coach agrees, it's one game.  If the coach disagrees, they coin flip for the series format.  But they are almost always a three game series.

There are six classifications based on school attendance.  This is only on the largest classification, 6A.

Each sport produces two "State Champions" in 6A.  There are four regions.  A grouping of two regions produces a "State Champion".  Each region has 8 districts.  Each district has 8 /10 teams and sends 4 teams to the playoffs.  So 64 playoff teams produces a state champion.  Only the final four teams go to "State".  The games are played at Disch/Falk (Univ of Texas) and Dell Diamond (Rangers AAA field).

So 12 playoff victories will give you a state championship, which could be up to 18 games.  The state finals are the weekend of June 7th.

(I wrote all this down for me to understand it.)

Colorado (speaking only of 3-5A):

32 team bracket. I'll use 3A as an example. There are 6 conferences. The top two from each conference (as decided by conference rules) get playoff berths. After that, the next 20 teams are chosen strictly by RPI for at-large berths. 

The two rounds are called "regional" though there is nothing regional or geographic about placement. The six conference winners and next to highest RPI teams get home field "pods." Those eight are seeded by a committee as seed 1-8. Teams are then distributed by RPI - 1 vs. 32, 2 vs. 15, etc. with the exception that teams from the same conference cannot play each other in the first round and the bottom eight seeds can be adjusted for geographical purposes. The first two rounds (pods) are held Saturday and are single-elim. The eight regional winners then move on the next Friday/Saturday to a double-elim bracket. Four teams survive that and move on the next Friday/Saturday to the final four.

California Southern Section. 7 Divisions, with D1 being the highest. 490 schools playing baseball. The number of schools in each division varies significantly, with the added wrinkle that starting this year, teams are placed in divisions based on their performance the past two years, and there will be movement each year -- sort of like the English soccer system, where the bottom teams in one division are relegated to the lower division, and the top teams move up a division. So part of the justification for D1 having only 42 teams (in years past it had about 70) is that it should be darn close to the top 42 programs (at least based on the last couple of years -- but it can obviously be off if a school is particularly strong or weak this year).

For D1, in years past there were play-in games for the final five spots. Not sure if that is still the case. But after play-in games, it is a 32-team, single-elimination tournament, with two games per week. Of the 32 teams, roughly a dozen will be ranked in the Top 100 teams in the country, per Maxpreps. Championship game at Dodger Stadium this year. 

GA...hopefully someone can explain better.  We are so big we have divisions. Biggest division is 7A or as we like to write it AAAAAAA.  Each region (there are 8) within a division sends their top 4 teams to the playoffs. 

32 teams begin the event. Game format is best of three, double header on Thursday, third game on Friday if needed, down to the sweet 16. The following week repeat that and you have the elite 8, then 4, then 2, then state champs PER DIVISION.

Ive attached the bracket for 7A.

We have four classes based on population.

Each class is divided into eight sections. Because of the varying number of schools in each class, a section in a lower class has more schools than one in a higher class, but within the class, each section is equal, give or take one. All schools qualify for the section tournament, which is seeded by the coaches in that section. The section tournament is double-elimination for the final eight teams; if sections have more than eight teams, they are single-elimination to that point.

Each section champion advances to the state tournament, which is single-elimination with a consolation bracket.

North Carolina brackets.    I believe 4th round games and beyond are best of 3.  The games prior are all single elimination.
